Today, we talk to Professor Frank Scheer from Harvard University all about one of the most important things that we do every day: sleep. For many of us, sleep may seem like a waste of time or an inconvenience. In fact, sleep is one of the most vital ways to maintain our health. Today, we learn why sleep quality is just as important as sleep quantity. What are the different phases of sleep and their functions? How do caffeine, alcohol, and sleeping pills affect our slumber? Are alarms good or bad? Should we be taking naps? If you feel tired all day, or can't seem to get a good night's rest, this is the episode for you!

We usually think of stress as a "bad" thing, something to be avoided--but is stress actually bad for our health? How does stress affect our eating and our food choices? Why do some of us gain weight when we get stressed, while others lose weight? This week, we talk to Professor Daryl O'Connor of University of Leeds all about stress, food, and our waistlines.
